IMPROVEMENT IN GOMPRESSION-GOGl-IS.

TOALL-WHOM IT MAY QONCERN:

Be it known that I, CORNELIUS A. HoWARD,`of New Haven, in the county ot' New Haven, and State of Connecticut, have invented a new Improvement in Compression-Cocks; and I do herebydeclare the following,-

when taken in eonnoctionwith theaecompanying drawings, and the letters of reference marked thereon, to be u.'

lull, clear, and exact description of the same, and which said drawings constitute part ofthis specification, and i represent, inl Figure l, a vertical cntralscction, closed by the turningoi the cock vto the left,

Figure 2 a vertical central section, open by thelturning of the cock to theifront, and in Figure 3 a like section, closed by turning the 'coclr to the right.`

This inventionrelates more particularly to what are called basin-cocks, or such as are used upon set basins, the nozzle of the cocli being arranged so as to be turned either to the right or left,'the object heng the construction of thecock s o that it will be Closed when turned either to the extreme right or left, and wide open at intermediate points; and thc invention consists in the arrangement of-a valve operated by a screw upon the plug, so that the said screw operates to Close the valve down upon the -inlet when turned in one direction, and close the end of the' plug when turned in the opposite-direction, 'and so as to open from the inlet to the plug when in an intermediate position.

In order'to the clear understanding of my invention, I will fully describe thc same as illustrated in the accompanying drawings. v

A is the shank, to which the supply-pipe is attached in the usual manner, and upon the said shank thebase, B, is formed in the usual manner, the base, B, forming a chamber, within which is placed the valve C, the said valve boing of less diameter than the chamber, so that a space will be left around the valve, as seen inthe severaltigurcs, and is formed with v'an opening, a, through the valvefrom side tosi'de. A

D is the plug, provided with'a nozzle, E, in the usual manner, and attached to the buse by means ofthe cap, F, at the upper end, and so asto hold the plugin position, and pack the joint, as seen in the several figures.

I The lower end of the plug has 'athread eut upon its outer surface, andthe upper end of the valve a correspond- 'ing internal thread, so that the plug will screw. into the valve,` as seen in the several drawings; therefore, turning'the plug from right to left, and vz'ce versa, it will be seen that as the plug gan, by--its attachment, have no vertical movement, the valve will he drawn up on the plug or forced down, as the case may he, the valve being prevented from turning by a projection, d, upon the side of the valve, working in a groove inthe chamber within the base. The length of the plug is such, that when the valve is down hard upon andso as to close the inlet I-I, the lower end of the plug will be open into the space a, as seen in iig. 1, butwhen turned half around to the right, lthen the val've has been raised by drawing the valve up on to the plug, but not sutlieiently high for the valve to strike and close the plug; therefore the water will iiow into the chamber and through the passage a into the plug, and out, as denoted by arrows, but, when turned tothe extreme right, then. the valve will have been so far raised as to close the end of the plug, as seen in iig. 3. '.lhus Vit will be seen that it will he impossible to turnthe valve to the right or left beyond a certain point, and that certain point always closes the cock.

I do not wish to be understood as broadly claiming a compression-cock, or one which clgscs by turning to the extreme right or left, and wideopen at intermediate points, as such construction is not new.

Having thus fully described my invention, what I claim as new and useful, Vand desire to secure by Letters Paten-tfis* V v The valve C, constructed with the passage a, and arranged within the chamber B, and combined with the pluglD, when the said plug D is arranged so as to operate the said valve to close the inlet at one extreme and the plug at the other, and open at intermediate positions, substantially in the manner herein set forth.

' CORNELIUS A, HOWARD.
